A New Perspective on P-Violation: Examining Event Plane Distribution Across Centralities

This presentation by Vasily Dzhordzhadze, delivered at the BNL CP Group Meeting on February 19, 2009, investigates the distribution of event planes across various centralities in particle collision experiments. The study reveals that event plane distributions differ significantly across centralities, highlighting the impact of detection efficiencies on these distributions. It emphasizes that the correlation parameter calculations may be inaccurate if detection efficiencies vary with centrality, underscoring the importance of understanding these distributions in the analysis of collision data.

  11. Summary • Event Plane distribution for different centralities are different, which reflects different detection efficiencies at different centralities -> EP efficiency varies with centrality and variation is significant! • The correlation parameter calculation is not correct if efficiencies are varying with centralities 11
